记录链接的分块方法比较

A Comparison of Blocking Methods for Record Linkage

Rebecca C. Steorts, Samuel L. Ventura, Mauricio Sadinle, Stephen E. Fienberg

摘要:

记录链接试图合并数据库,并在唯一标识符不可用时删除重复项。大多数方法使用分块技术来减少与记录链接相关的计算复杂性。我们回顾了传统的阻塞技术,通常根据一组字段属性对记录进行分区,并考虑了两种称为局部敏感哈希的方法,有时称为“私有阻塞”。“我们从召回率、缩减率和计算复杂性方面比较了这些方法。我们评估这些方法使用不同的合成合成的合成材料,并得出结论,讨论隐私相关的问题。

英文摘要:

Record linkage seeks to merge databases and to remove duplicates when unique identifiers are not available. Most approaches use blocking techniques to reduce the computational complexity associated with record linkage. We review traditional blocking techniques, which typically partition the records according to a set of field attributes, and consider two variants of a method known as locality sensitive hashing, sometimes referred to as "private blocking." We compare these approaches in terms of their recall, reduction ratio, and computational complexity. We evaluate these methods using different synthetic datafiles and conclude with a discussion of privacy-related issues.
